No picture needed for this one...you can make a big sanding block by buying a 3x24" sanding belt, and cutting a 1x4 to the correct length for a tight fit in the belt. Very useful.
Next, this portable bandsaw works real well and doesn't take up much space, if you mount it on the wall. Add a big metal platen and you have a good bandsaw that will cut anything. It does lack for throat space though. Buy used at pawn shops and save money. (Yes, the trigger is strapped "pulled")
If you don't have a vise on your drill press, this gadget is handy for holding handle material for drilling through, like antlers or blocks of wood. Made with flooring scraps and all thread and wingnuts.
